“Many thanks for your help at the end of last year. We especially appreciate your dedication to ensure the claims made the deadline, at what was a very busy time for us. I certainly agree that R&D claims are worthwhile and we will certainly want to make another claim.”

We have been working with LimestoneGrey since they started. Their knowledge on R&D claims is exceptional and we have no hesitation in referring our clients to them.

Advantage Accountancy & Advisory Ltd, Cardiff

Having experienced the preparation and submission of several R&D submissions in the past, I knew how onerous and time-consuming the process could be. I was only too pleased to meet with the team and be reassured that he would simplify the process and could provide advice and direction as to how the submission should be put together. We were happy with the size of the claim as it was larger than we anticipated, and due to the quality of the submission HMRC quickly processed the claim.

Fintech Company, Cardiff

We have experience and expertise in working with a range of companies, whatever the size or sector. No two claims are ever the same. We tailor our service to meet the needs of each client, guiding you through every stage of the process.
